👉 Lambda engineering refers to the specialized practices and tools used in managing and optimizing Lambda functions, which are serverless computing components designed for scalable, event-driven applications. It encompasses the entire lifecycle of Lambda functions, from development and deployment to monitoring, scaling, and cost management. Key aspects include writing efficient, stateless code, leveraging AWS Lambda's event-driven architecture to trigger functions based on various AWS services or HTTP requests, and utilizing monitoring tools like AWS CloudWatch for real-time insights into function performance and errors. Lambda engineers also focus on optimizing cold starts, managing dependencies, and ensuring security and compliance. By automating deployment pipelines with CI/CD tools and implementing robust error handling, they ensure seamless integration and high availability of serverless applications, making Lambda a cost-effective solution for building scalable backend services.
